Until more channels drop on this board (there's already one gone and it isn't really serviceable so I'm told) ...




I find that assessment hard to believe.

However, due to labor costs for disassembly, troubleshoot and reassembly time, what they might have been told is that it is not "cost effective" to go after the one bad channel at the time.

One trick I've seen done to boards with no LEDs on the Solo button might work for you -- the fellow very carefully darkened the side edges of the Solo buttons such that he could tell whether they were in the Up or Down position a bit easier. He used a permanent felt tip marker and something to mask the tob of the board such that only the sides of each button ended up being colored darker.

Might work for your particular board, might not, just something to consider...
